One of the objects of my present invention is to provide a combustionengine with simple means for self-ignition, when using crude oil asfuel.

Another object of the invention is to provide simple means for making atwo cycle engine adaptable to speed variation without misfiring.

To the attainment of the foregoing, the invention consists ofimprovements which are hereinafter described and definitely claimed. j

The accompanying drawings show the improvements in the combustionengine, but I believe that the said drawings are sufiicient to makeclear the invention in which a reference numeral is applied to designatethe same part throughout, but I am aware there may be modificationsthereof. 20'
